Jobtailor; Dearborn (MO); On-site; USD 110,000 - 150,000; Full time

Job summary

Jobtailor in Dearborn, MO, is seeking a Senior Powertrain Calibration Engineer to lead development testing across chassis and engine dynamometers using the 6.7L Scorpion platform. You will own Tier 4 chassis certification deliverables and coordinate cross-functional calibration activities.

You should have 3+ years in heavy-duty diesel emissions calibration, hands-on experience with CANape/INCA, DOE methods, and data-driven validation to balance emissions, fuel economy and drivability.

Qualifications

• Bachelor's degree in Mechanical, Electrical, Automotive Engineering or related field.
• 3+ years of experience in powertrain calibration focused on heavy-duty diesel emissions and chassis certification.
• Experience with 6.7L Power Stroke/Scorpion engine platform preferred.
• Proficiency with ETAS INCA or Vector CANape and CAN protocols.
• Deep understanding of EPA/CARB Tier 4 emissions regulations and chassis certification procedures.
• Experience with diesel exhaust aftertreatment systems (DOC/DPF/SCR).
• Mechanical and electrical wiring skills for prototype setup.
• Master's or PhD preferred.

Responsibilities

• Lead development testing across chassis dynamometers, engine dynamometers, and Super Duty test vehicles with the 6.7L Scorpion engine.
• Use virtual vehicle analytical simulations to front-load calibration development and demonstrate Tier 4 system capability.
• Own calibration deliverables required for Tier 4 chassis certification and regulatory documentation.
• Conduct sensitivity studies to balance emissions, fuel economy, performance, and drivability.
• Establish preferred control-variable values using data-driven approaches.
• Coordinate calibration of diesel engine, fuel system, turbocharger, EGR, aftertreatment, transmission, and driveline.
• Apply DOE methods to map calibration spaces and define robust operating strategies.
• Lead prototype system setup and commissioning in test environments.
• Document and present calibration progress and Tier 4 status to leadership and teams.
